Supersymmetric particles generated?

This article from yesterday (April 7, 2008) is a bit hard to follow, but it states:

"He and his team have created new fundamental particles in the lab that may have existed at the time of Big Bang, the creation of the Universe. The team is busy analysing the properties of the particles. It is presumed that these particles known as super symmetric particles constitute the mysterious "Dark Matter"."

Has anyone heard of anything related to this research? Did they actually create supersymmetric particles at Fermilab?

I think this is just another case of bad science journalism, which is more or less everywhere.

There ARE signs of SUSY in some standard model transitions---for example the b->s gamma operator receives contributions from SUSY particles generically, and it is a classic SUSY signature. The measurement used to be SMALLER than the SM prediction, which means that SUSY was very tightly constrained. The SM calculation was repreformed about a year ago, and the measurement is now ABOVE the prediction (by something like 2 sigma, which isn't good enough to claim discovery). There are also a few other signatures that people have been excited about lately---g-2 of the muon, for example (though this measurement is tough to fit with the simplest SUSY models).

I would approach this claim with a healthy dose of skepticism. While the concept of supersymmetry is a well-established theory in particle physics, there is currently no experimental evidence to support its existence. Therefore, any claims of creating supersymmetric particles in a lab setting would require extensive and rigorous testing and verification before being accepted by the scientific community.

Additionally, the article does not provide any specific details about the experiment or the particles that were supposedly created. Without this information, it is difficult to fully evaluate the validity of the claim. It is also important to note that the article does not mention any peer-reviewed publications or other sources that confirm this breakthrough, which is a crucial step in the scientific process.

In conclusion, while the idea of creating supersymmetric particles in a lab is certainly exciting, it is important to approach this claim with caution and wait for further evidence and confirmation from the scientific community before accepting it as fact.
